Mayor candidate, Edgar, claims that 55% of the city residents prefer to have him win the election. A researcher randomly surveys 940 city residents and 403 of them chose Edgar as their preferred candidate. Perform a hypothesis test, using the five-step process, to test whether the proportion of city residents who prefer Edgar as the mayor is less than 0.55 .

A poll done for Newsweek found that 13% of Americans have seen or sensed the presence of an angel. A contingent doubts that the percent is really that high. It conducts its own survey. Out of 76 Americans surveyed, only two had seen or sensed the presence of an angel. As a result of the contingent’s survey, would you agree with the Newsweek poll? Perform a hypothesis test, using the five-step process, to test whether the proportion of Americans who have seen or sensed the presence of an angel is less than 13%.
A public opinion organization wants to know if opinions on gun control laws have changed over time. A poll conducted in 2006 found that 55% of people favored stricter gun laws. A poll conducted in 2018 surveyed 250 people and found that 153 people favored stricter gun laws. Perform a hypothesis test to see if the results of the survey provide evidence that the proportion of people favoring stricter gun laws has changed from 2006 to 2018. For a hypothesis test, what would your hypotheses be? Find the p-value? Regardless of your answer to the previous question, let's say you find the p-value is 0.15. If alpha = 0.05, what is your conclusion? Group of answer choices Reject null hypothesis. We have evidence that the proportion favoring stricter gun laws has changed. Reject null hypothesis. We do not have evidence that the proportion favoring stricter gun laws has changed. Do not reject null hypothesis. We have evidence that the proportion favoring stricter gun laws has…
Microsoft would like to advertise that more than 30% of all its customers have more than two Microsoft products in their homes. To support this advertisement, Microsoft hires a statistician and she randomly selects a sample of 200 Microsoft customers and finds that 75 have more than two Microsoft products. Does this evidence support the advertisement? Use α = 0.05 to conduct a hypothesis test using the p-value method.
Last year, 46% of business owners gave a holiday gift to their employees. A survey of business owners conducted this year indicates that 35% plan to provide a holiday gift to their employees. Suppose the survey results are based on a sample of 60 business owners. a. How many business owners in the survey plan to provide a holiday gift to their employees this year? b. Suppose the business owners in the sample did as they Compute the p-value for a hypothesis test that can be used to determine if the proportion of business owners providing holiday gifts had decreased from last year. c. Using a .05 level of significance, would you conclude that the proportion of business owners providing gifts decreased? what is the smallest level of significance for which you could draw such a conclusion?
Minnesota had the highest turnout rate of any state for the 2016 presidential election.† Political analysts wonder if turnout in rural Minnesota was higher than turnout in the urban areas of the state. A sample shows that 654 of 872 registered voters from rural Minnesota voted in the 2016 presidential election, while 378 out of 525 registered voters from urban Minnesota voted. (a) Formulate the null and alternative hypotheses that can be used to test whether registered voters in rural Minnesota were more likely than registered voters in urban Minnesota to vote in the 2016 presidential election. (Let p1 = the population proportion of voters in rural Minnesota who voted in the 2016 election and p2 = the population proportion of voters in urban Minnesota who voted in the 2016 election.) H0: p1 − p2 ≤ 0 Ha: p1 − p2 > 0 H0: p1 − p2 ≠ 0 Ha: p1 − p2 = 0 H0: p1 − p2 < 0 Ha: p1 − p2 = 0 H0: p1 − p2 ≥ 0 Ha: p1 − p2 < 0 H0: p1 − p2 = 0 Ha: p1 − p2 ≠ 0 (b) What is the…
